Forms 2
Try viewing this in a browser, filling out its information, and clicking "Sign
Up". As you can see, at the moment the page doesn't do very much. You are
just returned to the same page, with the fields you filled out cleared again!
Our ASP page so far...
What we need to do now is add some code to process the inputted data. ASP provides
the Request.Form property for retrieving posted form information, and uses the
following syntax:
Request.Form(FieldName)
First of all, we need a way to detect if the information has been posted or
not - otherwise, we won't know whether to display the form, or process it. In
the original page, we included a hidden field called posted. Although
the user couldn't change it, it is a useful check to see if the form has been
posted. If it has, the field will have been sent along with everything else,
and its value will be 1. If the Sign Up button has not been clicked (and therefore
the data not posted), its value will be nothing. So, to check if the form is
posted or not, we can use
<%
If Request.Form("posted") = 1 Then 'form posted
Response.Write "<p>Thankyou for signing up</p>"
Else 'display the form
%>
<form action="forminput.asp" method="POST">
Your Name <input type="text" maxlength=20 name="Name"><br>
Your Email <input type="text" maxlength=100 name="Email"><br>
<input type="hidden" name="Posted" value="1">
<input type="submit" value="Sign Up">
</form>
<% End If %>
At the moment, however, we can't really do anything with the data posted, until
we know how to add it to a database. This is covered next.
